Re: Size of foam balls please

These balls even right off of the manufacturing line won't be the same

One of our POOF balls weighed 180g and another was 183g

NO. They are different. The soccer ball is larger.
I will prove this later tonight and provide a link.

Stay tuned.

Elgin,
Just the model name per the manufacturer should be proof enough:
See the manufacturer's sites regarding these products:
Soccer Ball
Basketball

Re: Size of foam balls please

We measured three balls as follows:
180g
181g
183g
The scale is only good +/- 1g though.
(That's about 6.3 oz. (180g) for the metrically challenged.
For diameter, we measured just a hair under 6.875 for all three, they are very consistent.

There is a thickening, a heavy 'lump' in the middle of the black side (well, it's black on our three plus another one I saw) that is heavy enough to cause the ball to always stop with that spot down.

The skin is very thin - how do you describe it? - much like the thin skin of most any molded foam ball you have even seen. It is not open-pored like the surface of a cut piece of foam rubber.

Hope this helps.

Don

Re: Size of foam balls please

I weighed one that was 185.327g. Why could our school possibly need a scale that measures milligrams? I have no idea.

Re: Size of foam balls please

OK, now that we got the rest of our order, we measured a total of 20 balls.
Average weight is 183.5 grams
Standard deviation is 2.55 grams

We unscientifically noted that balls also have different levels of hardness, and it doesn't correlate to weight. For example, our 187 g ball is a lot softer than a random 183g ball (as measured by pushing on the face opposite the hard spot).

With that being said, I don't think 3 grams in either direction will matter much.

Don
